          Defensive efforts to patch vulnerabilities have little effect on exploits. They usually die from unrelated code churn.pic.twitter.com/cVZRZwrVzQ

          AGAIN: efforts to patch or disclose your way to killing exploits don't work (*cough* Project Zero). Most die from code refactors.pic.twitter.com/tXF5rFI98J

          Bounties have little overlap w exploit development. Not in skill required, techniques developed, or bugs discovered.https://twitter.com/withzombies/status/839870870545850368 …

          To those dismissing this RAND report: Ignore it at your own peril. This is the best data ever released on real exploit development, period.

          Sort of like how an SE leverages small incremental bits of information that probably seem inconsequential, individually.
